To all whom is may sonne/ra s and @Hann l5. Momes, citizens or the Lnited State;

esiding at Conshohocken, in the county ,iilontgoniery and State of Pennsylvani have invented certain' new and'useful improvements in @ildelleotors for Engine-Cylinders; and wedo declare the following to ",-e a full, clear, and exact description oi' the invention, such as will enable others skilled in the ari; to which itappertains to inalie and 'the saine.

@ur invention rela-tes to einents in internal combustion engines obiect to provide an extremely simple and inexpensive, yet a l hl v eiiioient means to prevent oil throrwn reaching the spark. plug and fouling the saine. )in carrying ont this end, provide an internal Piange for tl ie cjfli^ der and such flange may either he formed as an integral part ol the cylinder, or oarriel hy vthe usual gasket employed between the eylinder and the cylinder heed, said iiane'e being arehed in transverse section to eleotively delieet the oil.

Figure l is a ver? r or i gine, showing the oi formed on the oyliinler head Fig. 52- is View similar lo ii' l, hotillns- "trating the flange formed as an inzegial part of the cylinder head.

ln the drawing above Iinfiel-y described, the numeral 'l designates the cylinder mi an automobile or other engine 2 has reference to the piston operating in said Cylinder, 3 refers so the' usual removable cylinder head, and e indicates the sparelnm A gasket is provided between the o n er head and the remainder oilz the e jlieder and 3 vided witl an opening (l Ylor eonnnunioat with the oy? ler t opening is usoally (flush wit. the Wall and does not in any manner Check the oil thrown. npr Y if' ton i2, and eonseqaer j f' spark plug; thereof or piston, from ln the present invention, however, the opening l is smaller than usual and the por tion of the gasket around said opening is stamped to forni a flange 7 of arch shane in i transverse section. This flange extends in- `War'dly from the cylinder wall and due to this shape` it will check any oil thrown un Wardly by the piston and deflect' such oil away from the spark plug, so that Laiding of the latter Vis prevented. i 65 ln the forni of the inif'ention shown Fig. :2, the flange 7 is casi as an integral part ol the cylinder head at the june i e of said head with the cylinder l and i the saine shape as the flange T shore 7o scribed. This Construotion may no lowod if desired, but it is preferable to provide the flange on the gasket instead on the cylinder head, in order that changes in construction of the usual motor will 'not he 7 necessary.

From the foregoing, taken in Connection with the accompanying drawing, it nfl.. seen that although our invention extremely simple and inexpensive n it will he highly eflicient and desirah the lpurpose intended, and sinee pre -the best results are obtainable 'from tails disclosed, they may well o e ioli We vvish it understood, however, that ivi inthe scope of the invention ce.' numerous minor changes may well he F or instance, although the lian t 7 Y Y are shovvn oi' such shape as to ect the oil bach against the cylinder vvall as the piston descends, they might well be of any other adequate rnlation'.
